Changes in version 0.8.4 (2022-04-12)                  

  - Vignette is now included.

                Changes in version 0.8.3.1 (2022-03-20)                 

  - Hotfix in function is_scalar which is an issue in package jti

                 Changes in version 0.8.3 (2022-02-07)                  

  - normalize now returns 1 if applied to a numeric

                 Changes in version 0.8.2 (2021-11-24)                  

  - Bug fixed when mult/div two unities
  - Bug fixed when calling div(x,y) with x being a scalar. The result
    was the same as div(y,x).
  - numerics can now be marginalized. The result is the numeric itself.

                 Changes in version 0.8.1 (2021-07-05)                  

  - as_sparta.data.frame does no longer convert to an array first
    (expensive) and is therfore much more efficient now.

                 Changes in version 0.8.0 (2021-06-18)                  

  - marg is now more efficient when y is character(0)
  - A sparta_unity_struct can now be sliced if drop  TRUE=.
  - Better argument checks in slice
  - mult and div is now faster when one of the tables is a subtale of
    the other. This is especially useful in connection with Bayesian
    networks and the Junction Tree Algorithm.
  - sum, normalize, get_vals and vals now works as expected on
    sparta_unity class
  - New functions: sparta_rank and table_size
  - as_array now works for sparta_unity

                 Changes in version 0.7.3 (2021-04-22)                  

  - Bug fixed when argument drop is TRUE in slice for tables that should
    reduce to one row.

                 Changes in version 0.7.2 (2021-04-03)                  

  - The new print method turned out to cause problems in the long run.
    Printing a sparse table now prints columns as rows again with the
    corresponding value attached to the right.
  - marginalizing is much more memory efficient now. Especially for
    massive tables.

                       Changes in version 0.7.1.0                       

  - Multiplication of unity tables was not correct due to the new rank
    argument. The fix was to multiply the rank of the tables.
  - Print method changed to print cells as columns which is also how the
    sparse tables are represented under the hood.
  - New functions (see documentation):
      - sparsity: determines the ratio of non-zero cells and the size of
        the statespace.
      - as_df: convert a sparse table to a data.frame. Either with or
        without zero cells
      - get_values: The same as the existing vals

                 Changes in version 0.7.0 (2020-12-16)                  

  - unity tables now have a rank attribute which is just the unique
    value that all cells have. Because of this, a unity table can now be
    multiplied with a scalar. And regular sparta tables can be
    multiplied with unities of different rank. As a consequence, unities
    can now be marginalized also.

  - New function equiv to test if two sparta objects are identical

  - Fixed a bug when assigning dimnames to the result of multiplication

                 Changes in version 0.6.1 (2020-11-24)                  

  - marginalization is now faster due to some refactoring

                 Changes in version 0.6.0 (2020-11-09)                  

  - Prevent print from printing dimension names
  - A bug, due to wrong sorting, that manifested in both marg, slice,
    mult and div has been fixed. These functions were prone to errors
    when the number of variables exceed 10.
  - It is now possible to multiply and divide sparta tables with a
    scalar where the scalar can be either of the two inputs. Prior to
    v0.6.0 the scalar had to be the second argument.

                 Changes in version 0.5.0 (2020-10-15)                  

  - First release
